What material is ST37-2 steel plate?

ST37-2 steel plate is a kind of ordinary structural steel used in construction and underground engineering.

This material corresponds to the Chinese standard and is equivalent to carbon structural steel Q235B (the old brand is: A3-B)。

Another: Because ST37-2 steel plate is similar to the national standard high-quality carbon structural steel 20 steel, it can also be replaced by 20 steel.

The chemical composition of ST37-2 steel plate is as follows:
C: 0.17-0.20
Mn <1.4
P and S <0.045
Si is not specified.

Delivery status of ST37-2 steel plate: hot rolled, probe rolled or normalized. Technical conditions: According to the chemical composition and mechanical properties of ST37-2 steel plate, impact, flaw detection, Z-direction, composition control, and performance requirements beyond the standard can be added when ordering.
